The La-Sr-Mn-O films were deposited on Si(100) substrates by DC magnetron sputtering and followed by air annealing at 973 Kfor 1 h. The microstructure and tempe
Micro-and nanocrystals cubic-phase SrF2:Yb3+/Er3+ upconversion luminescence phosphors were synthesized via a facile hydrothermal route in the presence of differ
The nanocrystalline and amorphous Mg2Ni-type Mg2-xLaxNi (x=0, 0.2) hydrogen storage alloys were synthesized by melt-spinning technique. The as-spun alloy ribbon
